"Donating blood saves lives" - is not just a motto blood banks use on World Blood Donor Day, it's also a step toward a healthier India.A Lancet report revealed that India faces the world's largest blood shortage, with a national shortfall of over 41 million units. The demand for blood outpaces supply by more than 400%.On average, a unit of blood is needed every two seconds across the country. While 14.6 million units are required annually, there's still a persistent shortage of 1 million units.advertisement
But amid this crisis, experts say blood donation doesn't just benefit the person who needs it but can also offers significant health perks to the donor."Donating blood is often perceived solely as a charitable act that helps others. But it also carries health benefits for the donor, particularly in terms of cardiovascular wellness," Dr. Ujjawal Kumar, senior consultant, cardiology, Sarvodaya Hospital, told IndiaToday.in.A MINI HEALTH CHECKBefore donating blood, you undergo a quick health screening. This can flag early signs of health issues like high or low haemoglobin levels, blood pressure irregularities, or rare blood types.

Dr. Kumar explained that iron regulation plays an important role."Iron is essential, but in excess, it can generate free radicals that damage blood vessel linings. This can increase the risk of heart attacks and strokes. By donating blood, you reduce excess iron, lowering that risk," he said.This is quite helpful for people with hereditary hemochromatosis, a condition where the body produces too much iron. These individuals are often advised to donate blood regularly, helping both their own health and blood banks in need.THINNER BLOOD, BETTER FLOWBlood viscosity, or thickness, can affect how hard your heart works. Thicker blood increases the risk of clots and puts strain on the heart.

"Blood donation helps thin the blood temporarily. This promotes better flow and can reduce clot-related risks," said Dr. Kumar.Each time you donate blood, your body is prompted to produce fresh blood cells. This renewal process helps maintain a healthy blood profile and support vascular health.Donating blood regularly also helps control blood pressure. "In certain individuals, especially those who suffer from borderline or mildly elevated blood pressure, donation can have a modest lowering effect. This is likely due to the temporary reduction in blood volume and improved vascular function, which reduces strain on the heart and arteries," added Dr. Kumar.Moreover, each blood donation triggers the body to produce new blood cells, which may help maintain a healthy blood profile. Some studies have suggested that this renewal process might have indirect positive effects on overall vascular function.THE FEEL-GOOD FACTORThere's also a psychological benefit to donating blood. Acts of kindness like this are linked to reduced stress, lower levels of cortisol (the stress hormone), and an improved sense of well-being - all of which have long-term heart health benefits.

Many worry about weakness or fatigue post-donation, but with proper hydration and rest, most people recover quickly.Dr. Kumar highlighted that blood donation should complement, not replace, your existing heart care routine: "Maintain a balanced diet, exercise regularly, avoid tobacco, and monitor your cholesterol and blood pressure."So the next time you see a blood donation drive, remember: you're not just saving lives, you're gaining health.Trending Reel
